Objective:To study the autophagy of artesunate(ART)on leukemic K562 cells and its possible mechanism. Methods:The inhibitory effect of ART on the proliferation of K562 cells was detected by CCK-8. The cell apoptosis was examined by the flow cy-tometry. Western blot was carried out to detect the expressions of LC3
p62
HMGB1 and Beclin1. Results:ART inhibited the proliferation of K562 cells in a dose-and-time dependent manner
with IC50 value of 30 mg/L at 48 h. In addition
ART could induce the apoptosis of K562 cells and the apoptosis could incease when combined with CQ. According to the results Western blot
ART could up-regulate the expressions of autophagy-related molecule LC3
p62 and down-regulate the expressions of HMGB1
Beclin1. Conclusion:ART shows the effects in inhibiting the autophagy of leukemic K562 cells. Its mechanism may be related to the down-regulation the ex-pression of HMGB1
Beclin1
and the inhibition of autophagic degradation
and that ART-induced inhibition of autophagy may eventually results in the death in K562 cells.
